Every Twitter troll needs someone to shut them down. Luckily, one guy who posted a long thread claiming that “depression isn’t real” had J.K. Rowling, Patton Oswalt, and a host of other celebrities to debunk him.

Oswalt, who has publicly discussed his struggles with depression, responded to a thread from Andrew Tate, a kickboxer and Big Brother contestant who describes himself in his Twitter profile as “toxically masculine,” that promoted harmful misinformation about mental illness.

Soon, other celebrities passionate about mental health chimed in to debunk a dangerous Twitter thread that claimed that depression isn’t real and that people suffering from depression are “too lazy to change” their lives.
